- IsagriFullstack DeveloperSOFTWARE PUBLISHINGSeptember 2023 - September 2025 (2 years)Beauvais, FranceI worked as a full-stack developer within a small team in charge of a parcel analysis satellite application for farmers. This app processed satellite data and agronomic metrics, with a high requirement for performance and reliability of processing, to meet the strict standards of the sector.🎯 Front-endDevelopment and continuous improvement of the interface in React, MUI, and Redux, with a high level of interactivity around maps, zones, and agricultural indicators.🛠️ Back-end & SystemsDesign and evolution of the ASP.NET backend, including:integration and optimization of nightly jobs (batch processing, data generation, internal synchronization),calls to various satellite APIs (WFS/remote sensing),improvement of robustness, logs, and error management.⚡ Optimizations & Reliability (my last role in the team)I was responsible for identifying and then correcting several technical limitations:front-end performance optimization (reduction of rerenders, memoization, Redux improvements),reduction of latency on certain critical endpoints,refactoring of backend parts for better readability, maintainability, and isolation of responsibilities,improvement of the stability of nightly processing (better asynchronous management, prevention of silent failures).🧩 Cross-functional workFull-stack project involving UI, business logic, agronomic models, network performance, and management of large data flows. I had to be autonomous on the entire technical chain: from the React component to the .NET job executed at night.Stack: React, Redux, MUI, React Native, TypeScript, ASP.NET, C#, SQL Server, Satellite APIs (WFS), batch jobs, monitoring and logging tools.
